I'm working through my first set of CA scales, following Glen's most excellent tutorial (thanks, Glen!). Question: the tutorial calls for rubbing compound. I don't have any handy at the moment. Will polishing compound work as a substitute? Second question: will the paste versions (as opposed to the liquid versions) work? Thanks guys.

PS: I'm convinced that the professional scale makers (such as Glen) make about $0.04 per hour making scales. I put 6 coats of medium CA on the inside of the scales and about 12 on the outside. It took forever! My hat is off to you pros.
